The placement cavity 10 is used to place materials for heating or cooling.
[0035] The needle plate 2 is a plate-like structure as a whole, and its shape is the same as that of the disk bottom 11, and its size is slightly smaller than that of the disk bottom 11. In this embodiment, the difference between the size of the needle plate 2 and the size of the disk bottom 11 is 1mm-4mm, so as to facilitate the placement of the needle plate; the needle plate 2 is installed (placed) in the placement cavity, and the lower bottom surface of the needle plate 2 is attached to the upper surface of the disk bottom 11, thereby achieving heat transfer between the two; a heat-conducting needle 3 is vertically arranged on the upper surface of the needle plate 2, and the heat-conducting needle is columnar. There are multiple heat-conducting needles 3, which are arranged in a matrix on the needle plate 2.
[0036] See also Figure 1 and Figure 2The heat conducting needles 3 are arranged in multiple rows, and the multiple rows of heat conducting needles are arranged equidistantly along the width direction of the needle plate 2. At the same time, the heat conducting needles in each row are arranged equidistantly along the length direction of the needle plate 2 to form a row and column arrangement.
[0037] In the present application, the tray body 1, the needle plate 2 and the heat-conducting needles 3 are made of heat-conducting materials, which are usually made of aluminum, copper or other metal heat-conducting alloys to achieve heat transfer.
[0038] In order to facilitate replacement of the needle plate to meet different usage requirements or to perform maintenance and upkeep on the needle plate, the needle plate 2 is detachably mounted on the disk bottom 11 by means of buckles or bolts.
[0039] See also Figure 1-Figure 6 In this embodiment, the needle plate is connected to the disk bottom 11 by bolts. Specifically, a bolt body 13 is vertically arranged on the upper surface of the disk bottom 11. The bolt body 13 is multiple and is arranged at the edge and center of the disk bottom 11. Preferably, it is arranged at the four corners and the center of the disk bottom 11 to improve the connection strength of the needle plate and ensure the fit between the needle plate and the disk bottom 11. The height of the bolt body 13 is less than the depth of the placement cavity. In this embodiment, the height of the bolt body 13 is 1 / 3-2 / 3 of the depth of the placement cavity; at the same time, a mounting hole 20 is opened on the needle plate 2, and the mounting hole 20 corresponds to the bolt body 13 one by one, and can allow the bolt body 13 to just pass through. A cylindrical nut 4 is threadedly connected to the bolt body 13, and the lower end of the cylindrical nut 4 contacts the needle plate 2, thereby realizing the compression and fixation of the needle plate. At the same time, the cylindrical nut plays a role of heat conduction.

In this embodiment, the cylindrical body is a regular hexagon or a regular octagon. A screw hole 40 is provided at the center of the lower end surface of the cylindrical body 41, which can be threadedly connected with the bolt body 13. In this embodiment, the height of the cylindrical nut is less than the depth of the placement cavity. After installation, its top is located in the placement cavity, that is, its top is located at the lower end of the disk edge; the lower end of the cylindrical body 41 extends radially outward , forming a clamping portion 42, the side wall of the clamping portion 42 is an inclined surface, forming a truncated cone shape, the lower bottom surface of the clamping portion 42 is a plane, and forms a clamping surface 42a, which is used to contact with the upper surface of the needle plate 2 and achieve clamping. By setting the clamping portion, the contact area with the needle plate 2 can be increased, the clamping force and the fixing reliability can be improved, and at the same time, the increase in the contact area increases the heat conduction area, thereby improving the heat conduction efficiency, that is, the cylindrical nut has the functions of fixing and heat conduction at the same time.

The structure with a large upper end and a small lower end increases the contact area and increases the structural strength of the lower end.

The first cylindrical body 31 and the second cylindrical body 33 are coaxially arranged, and the diameter of the second cylindrical body is smaller than the diameter of the first cylindrical body; at the same time, the first cylindrical body 31 and the second cylindrical body 33 can be connected by an inclined surface 32 to form a natural transition without a step structure.
